Abstract

The purpose of this research is to know the effectiveness of fly ash waste in marine concrete related to the average compressive strength to be used as a substitute for cement. The test is done for concrete base material, namely: coarse aggregate (gravel), fine aggregate (sand), fly ash, cement (PC = Portland Cement), water and additional material (superplasticizer). 10 cylinders were given each treatment with (0 %, 10 %, 20 %, 25 %) percentage of fly ash addition. The samples then soaked for 26 days in seawater. At 28th day, the sample was subjected to a compression test. Based on the results of analysis and discussion, then obtained: (1) The use of 10% fly ash amount will produce the biggest compressive strength  =  65.84 MPa; (2) When compared with the average compressive strength, the sample without using fly ash (0 %) has compressive power 62.02 MPa and 6.16 % increase in average compressive strength on the addition of 10 % fly ash 65.84 MPa, but in addition to 20 % fly ash there was a decrease of 9.13 % (56.36 MPa) and in addition of 25 % fly ash the average compressive strength decrease to 22.49 % (48.07 MPa).

Abstract

Abstract The use of the mountain seal used as a building block for concrete should be considered, based on current usage apart from being a light construction material for housing, mountain materials from these two places are used as the main aggregate material for building construction, water structures (dams), roads. and bridges located in the surrounding Malang-Kota Batu area To determine the size of the aggregate, the coarse aggregate is sieved using a vibrating sieve, while the fine aggregate is sieved by a hydraulic sieve. In the screening process, about 70% of the filtered must pass so that high efficiency and capacity can be achieved. The compressive strength test results obtained the average compressive strength value at 28 days of concrete for concrete with fine aggregate sand zone III and coarse aggregate (gravel) in the Batu City area is equivalent to 35.65 MPa. The results of the split tensile strength test showed that the average split strength value at the age of 28 days for concrete with fine aggregate sand zone III and coarse aggregate (gravel) in the Kota Batu area is equivalent to 2.51 MPa. The compressive strength value for normal concrete is 35.65 MPa, it should produce split tensile strength = 4.179 MPa according to the provisions of SNI T-15-1991-03 Article 3.2.5 (fr = 0.70√fc '). Even though the split tensile strength value obtained in the laboratory is only 2.51 MPa, this means that the quality of materials (sand and broken stone) from Batu City is not suitable for use as building materials. Because the number 2.51 MPa is relatively much smaller than the value of 4.179 MPa, it is only one of the factors outlined in the SNI T-15-1991-03 article 3.2.5.

Abstract

The pupose of this research is to observe the effect of water cement factors to the toughness of concrete :“How is the effect of water cement factors to the toughness of concrete?” Laboratory testing is done for concrete base material, that is aggregate: Rough (pebble), fine aggregate (sand), cement (PC= Portland Cement), water. The test object is in the form of a cylinder with mix design that have variation at water cement factors (cement water factors 0,35, cement water factors 0,40, and cement water factors 0,45) for 10 pieces, which is soaked for 26 days. On the 28th day, the object will be tested press.Based on analysis and discussion, then obtained that (1) From the mixed composistion based on Water Cement Factors, it is seen that the mixture using the lowest water cement factors, Cement Water Factors 0.35 will give a stronger press value and larger elastic modulus, 23,36 MPa at Cement Water Factors 0.40 (11,34%) and increased to 26,68 Mpa at Cement Water Factors 0.35 (27,17%). (2) Compared to the lowest Cement Water Factors, Cement Water Factors 0.35 will give a higher Work of Fracture ( Gf ). This is shown from Work of Fracture ( Gf ) to Cement Water Factors 0.45 = 31,445 N/m, increased to 34,582 N/m at Cement Water Factors 0.40 (9,025%) and increased to 35,582 N/m at Cement Water Factors 0.35 (13,156%). (3). Quantitatively the hardness, the bigger value of power achieved will show the bigger concrete ductile. This is shown from Stress Intensity Factor (K) to Cement Water Factors 0.45 = 0,8267 N/m, incresed to 0,8664 N/m at Cement Water Factors 0.40 (4,80%) and increased to 0,9088 N/m at Cement Water Factors 0.35 (9,93%).

Abstract

Alternative cement replacement are widely observed due to environmental issues. The processes of cement production are indicated as one of the highest contributors in CO2 levels in the air. One of the substances used as alternative cement is fly ash because it is similar in nature to cement and the amount is abundant because it is a residual result of coal burning process in power plants. Generally, fly ash is classified into two types namely type C and F. Type C is rarely used because it is easy to harden. However, in further research, this type C has advantages in increasing the compressive strength of premature concrete. This research was made to obtain the optimum type C fly ash ratio with cementitious material on the mortar. Technically, the research was carried out by making mortar samples with a composition ratio of 1: 3, while the cement water factor was 50%. Then, the composition of cementitious is varied between PC and fly ash, starting from 0%, 25%, 50%, 75%, and 100%. Testing is conducted only in the first and second week to observe the development of the initial forces. However, not all combinations can be tested because the strength is too low. Only the 25% fly ash combination gives 20 MPa strength at 7 days, which outperforms a control sample of 19.36 MPa. Henceforth, the strength of fly ash samples tends to be lower when compared to control samples.ABSTRAK Bahan alternatif pengganti semen mulai banyak dicari karena isu lingkungan. Proses pembuatan semen terindikasi sebagai salah satu penyumbang tertinggi dalam kadar CO2 di udara. Salah satu substansi yang banyak digunakan untuk bahan pengganti semen adalah fly ash karena sifatnya serupa dengan semen dan jumlahnya melimpah sebagai hasil residu pembakaran tungku batu hara di PLTU. Umumnya, fly ash dikelompokkan menjadi dua jenis yaitu tipe C dan F. Tipe C jarang digunakan karena mudah mengeras. Namun, pada penelitian lebih lanjut, tipe ini memiliki kelebihan dalam meningkatnya kuat tekan umur prematur. Penelitian ini dibuat untuk mendapatkan rasio fly ash tipe C yang tepat dengan cementitious material pada mortar. Secara teknis, penelitian dikerjakan dengan membuat sampel mortar dengan perbandingan komposisi 1 : 3, sedangkan faktor air semen sebesar 50%. Kemudian, komposisi cementitious divariasikan antara PC dan fly ash, mulai dari 0%, 25%, 50%, 75%, dan 100%. Pengetesan dilakukan hanya pada minggu pertama dan kedua untuk mengamati perkembangan kekuatan awal. Namun, tidak semua kombinasi bisa diujikan karena kekuatannya terlalu rendah. Hanya kombinasi fly ash 25% saja yang memberikan kekuatan 20 MPa pada umur 7 hari, mengungguli sampel kontrol berkekuatan 19,36 Mpa. Sedangkan kekuatan sampel fly ash cenderung lebih rendah jika dibandingkan sampel kontrol. Kata kunci  : fly ash tipe C; mortar; kuat tekan.

Abstract

Mortar or species is one of the building materials which serves to glue the bricks, brick, and stucco. During this time still using portland cement mortar and lime as the main connective materials are expensive. Therefore we need an alternative other connective materials that have cheaper prices and predicted can improve the compressive strength of mortar. Alternative fastening material used in this study is waste from coal combustion, ie fly ash (fly ash). This study uses a mixture of cement and sand composition of 1: 3 at a weight ratio of fly ash to cement amounted to 0%, 5%, 10%, 15%, 20%, 30%. Samples were tested compressive strength and water uptake is cube-shaped sample with a size of 5 cm x 5 cm x 5 cm. Based on the results of research conducted showed that the addition of fly ash was found to increase the compressive strength of mortar and act as filler so as to reduce water absorption, which in get the most optimum composition occurs in the percentage of 15% of the weight of the cement with the compressive strength at 28 days amounted to 420.00 Kg / cm² and water absorption of 1.67%
